I'm also looking for a new locator, the Lowrance LMS 332c is at the top of my list right now. I'm just waiting for one of our local shops to get one in so that I can see it first hand.
I have a color hand held GPS and love it. So much easier to distinguish what you looking at in a glance, and I know the Lowrance locator I'm looking at blows away my GPS.
I was told that "today's" color units are just about like looking at a lap top monitor! I wish I could afford to go to a 7" screen though.....
Something else to note, Lowrance's web site has downloads available that you install on your PC.
They are product emulators, you can actually practice using which ever product that you downloaded....... very very cool
